Like the idea.
Personally I prefer the curved frame look. The only downside is the width of the frame would need to be relatively wide so as to allow the user to get into the seat.
A thought that springs to my mind is that it might be better for the end user to have the option to fit there own seat.
That way they could fit a full racing bucket seat should they so desire or for the more thrifty (or comfort conscious) of us out there you could go to the scrapyard and get a fully adjustable seat for $10-20 - ie tilt backrest back/forward, tilt seat of chair back/forward, raise up/down, lumbar support adjustment, slide forward/back, plus headrest. heck even electrically heated if you want. With the added advantage of saving on all those costly clamps and adjustable fittings.
OK, it's a bit more effort for the end user but how much hassle is it to undo/tighten four bolts.
Other thoughts: It would be nice to have the keyboard able to swivel out to the left or right instead of in behind or underneath the steering wheel. Personally I find it a real pain to have to reach over the wheel just to type on the keys - likewise to pull the keyboard out every time you need to type something.
Also might be nice to have some sort of sturdy fitting to clamp gearshift to left or right of seat at a level more akin to being in a car rather than having to reach up to the desk level to change gear.
With regard to monitor.
People that are prepared to pay for a set up like this are likely to be able to spend a few $. Therefore it may be prudent to provide an easy mounting system for a triple monitor setup, ie something a bit more aesthetically pleasing than a shelf wide enough to sit three monitors on - but also versatile enough just to stand/mount 1 monitor.
Being lazy it would be nice to see a drinks holder in there someplace as well.
Unfortunately not really practicle due to the huge variety avaliable but it would be nice to have the surround speakers mounted either side of the chair so that there isn't lots of wiring floating about, or even space for a reasonable sized sub-woofer to fit under the seat.
Anyway, those are my thoughts.
Regardless of what you come up with i'm sure it'll be of a higher standard than my current driving setup
And what about keyboard and mouse? It would be a bad idea to attach the steering wheel to the table so that you couldn't take it off. As for the keyboard - You could possibly make a little rectangular plate shaped as the steering wheel table and get some sort of bolt lock for it so it doesn't keep sliding out.
