My words in my own house are falling on deaf words, but at least people here can read and take advantage of what I have to offer.
Sorry, having a bad day.
Anyhow, these are my thoughts. Now, hardware solutions tend to be rock solid because they don't have to deal with the issues that having an attached PC might bring to the table. Good or bad, it depends on the perspective. When it runs, it runs great. When it crashes, it's ugly city man, and you're in the butt-crack of Ugly-Town when that happens.
I think the Chauvet product offers(MyDMX equivalent) storage of shows in the unit, but man, I wouldn't trust that unit as far as I could throw it. This is due to my past interactions with Chauvet, so I'm somewhat biased against them.
Lugging a laptop to a gig should just be part of your load. Do it. Trust me, if things take a dump, you've got a means of control. Well, depends on the dump. Might want to have a controller surface with some back-up programs stored in it. That's what I plan to do. Actually, mine is the reverse.
I intend to use my DMX Operator as my main thing for a while. Just as I learn MyDMX better. The DMX Operator won't dump on me and I'll just use a basic 8-color lighting scheme with no moving head stuff going on. Then, when I transition to MyDMX, I'll still have my DMX Operator handy. Should the computer solution dump, I have hardware back-up. Besides, the rack that the DMX Operator is will be with me at FOH anyways, so it's not like I'm packing anything extra. I carry a laptop to all shows now anyways, so again, nothing extra.
Being a beginner as you are, it's nice to plan ahead and put the cart ahead of the horse. You might want to work your want into where you want to be so you can learn from it. I just see "too much, too soon" and a disaster looming.
I'm not a big trusting person when it comes to wireless and protocols that don't use error correction. At least with 802.11a/b/g/n, there is the TCP packetting that handles error correction and retransmissions. Since you're also dealing with a fixed location, wireless just doens't make much sense. To me, more hassle than it's worth. I know it seems like "well, no wires means less hassle", and true enough, but really, if nothing's moving, why bother with wireless? I'm for reliability. Of course, I do concerts, so I have to be prepared for disaster because the show can't stop because something is pooping out on me.
I'd rather run the cable and do things that way. That's just me. There are great wireless DMX solutiosn, but I just don't see the purpose. Again, since I have to run cable anyways, what difference is another cable laid next to a larger cable? 2 Cat5's, a 56-pair whip and a DMX cable. BFD. It's on a reel, wind it up and go at the end of the night and I'm outta there.(well, that and loading 2.5 tons of gear back into the truck is fun too!)
Since DMX is a one-way protocol, there is no return to a transmitted signal. It goes THAT-A-WAY: out the controller and to the fixtures/switchers/relays/dimmers/movers/whatever. They don't talk back.
So, while TX and RX apples relative to the pespective of the gear involved, it's still basically a streaming signal travelling in one direction.
Elegant is one thing. Elegant is also a matter of opinion. Right now, I hear "lazy vs doing it right". Lazy COMBINED with doing it right is an elegant solution IF the lazy person worked long and hard to ensure no issues. I'm trying to steer you clear of wireless.
I think you're better off going to like the OptiSplitter to avoid super long cable runs and to centralize cable management. Just use extra DMX Terminators, which is no big deal or cost.
