We're looking to install a noise cancellation system at work and it would require large amount of speaker wire to criss-cross the CAT6 data cable we have in the ceiling. Any thoughts as to interference concerns between the two? Any suggestions on Web resources with more info? Thx!
Interference between ethernet and speaker wires

That's classified as low voltage cabling. Don't worry about it.
For the official specification you'll need to consult the EIA/TIA 568 standards.
-edit-
If it really bothers you (and cookie for actually thinking about the quality of your cable plant) then cross the cat6 runs at right angles. Even then you should be fine running parallel at 4+ inches. I don't remember the exact spec. If category cabling is actually installed properly (rare, patch panels need to be commonly grounded) it is just about impervious to noise.

Unlike regular 110/220 noise lines with a lot of high frequency spikes that can interfere with the Network signal.
Audio line flow is relatively clean, and thus source of noise has to come from harmonies of the core frequency. By the time 20kHz get harmonize to the frequency of the Network frequency nothing left to interfere.

Wyck, I'd strongly urge you to keep the speaker wires as far away from your cat5/cat6 cable as you can manage.
Because you have a commercial installation, just ask the cabling guys to run the speaker cable inside properly grounded metal conduit. This is common for current-carrying cables in a commercial environment anyway, and while it's not required for speaker cable it will prevent any sort of interference.
Depending on what problem you're trying to solve, you might also find it helpful to run the cat5/cat6 inside separate properly grounded metal conduits.
Speaker cable is trouble for data cable. Normally I'd give you an answer of the form "just do the best you can and don't worry about it." But that's one thing you really should do more for. It usually carries a decent amount of current, at a wide variety of frequencies, and the spectral content keeps varying.
