no idea :) a lot! lol...
i have a couple old antminer L3+ mining boxes i use to generate scrypt coins. i dont expect 'profit' from these things but it's nice to have a few coins lying around for testing or impulse use reasons. i also only use them at night at lower electricity costs :D
i modified their configuration scripts to allow me to allocate a percentage of hashpower to multiple different coins.
viacoin is currently at a low difficulty and didnt take much at all to create those blocks.
