Ummm.... why is it in altcoins, not at services ? Well never mind
I like the idea, 2% on each transaction might make it profitable for server owner, although I wonder if Bob wife wound't worry that her husband is using such services. I'm not entire sure but if I get it right, I can hide traces of my money flow but i can't hide fact that there are TiPS at beginning. Well still i like the idea of creating new kind of services. It makes this meta-industry much more interesting and definitely flexible. TiPS might be even only reason why someone would use meta-currencies.
Oh, and I'm afraid Bob would use TiPS to spend money on different... services
