new to mining, n00b question

[cevad]

Am new to mining and am currently using a couple of Block Erupters.  I was going to mine with 2 ATI 6870 cards, but decided against it due to heat and power cost issues.

I will be mining with a raspberry pi (once my powered hub turns up) and am also waiting for a Red Fury to arrive.

Is it possible to run 3 BE and a Red Fury together?  I'll probably use minepeon - am currently using BFGminer and a netbook.

Thanks,
cevad
