Seriously it's completely fine in the digital domain if the boards are relatively new, aren't crap (i.e. are Wisher/3M boards without those awful phosphor bronze contacts) and you're under about 10MHz and have enough decoupling capacitors and keep your signal paths relatively short. I've built pretty much this machine and it was frequency stable to about 8MHz and it only died after that because the clock was divided down from a 32MHz XO.
Stray capacitance isn't a mega problem unless you're doing analogue and require frequency stability or going above ~10MHz. The killer for digital is usually ringing on the high/low state transitions but if you look at the timing charts for most things this isn't that bad. Most digital stuff works pretty well if the signals are pretty fugly.
However, wave a scope or logic probe near it and all sorts of crazy shit can happen.
