Not really sure what you're asking. You can mine at any speed, the more important factor is the efficiency. Say I created a pinwheel that somehow performed a hash every time it spun fully around, I found it on the ground, and all it has to do is sit wherever it is. The hash rate will be almost uncountably low, but since it costs nothing (time, energy, material) it's technically "worth it" in that sense.
I would say don't invest money into something like a GPU to hash, regardless of the quantity of hashrate you will get out of it, as it will likely not repay itself with the hardware gearing up to be unleashed. ASICMINER, Avalon. Cairnsmore, etc. unless you get some crazy pinwheel type deal.
As for the hassle involved, if you factor that in, simply figure out what your time is worth to you. If I profit 1 cent a day and it took me 10 hours to set up, it's not worth it to me, but that's a personal thing (hey I'd make my money back in 3 years after all!).
Given the new state of bitcoin value, difficulty will likely shoot to astronomical levels, but not for a while, hardware is a huge bottleneck right now. End of year maybe 500THash? Really depends on how the manufacturers gear themselves up to deliver. Avalon is being iffy about their production capabilities (probably due to Chinese Govt stuff being scary), but on the flip side there are plans to sell ASIC chips directly to consumers to produce in whatever manner they see fit. BFL claims that they want to roll out an unlimited TH stream, but their production is still questionable.
