Unlike Tor, you can't access regular website/domain with I2P.
There should be ways to bridge out of I2P and back in again. Bitcoin is set to add a new IP announce format with a field designed to be big enough for v3 Tor hidden services and I2P hidden service IP formats (as well as CJDNS)
I've seen few article which mention it's possible with additional plugin (e.g. I2P Orchid), but i think there's privacy concern using additional bridge or plugin, what do you think?
I'm fairly sure that if Microsoft did come out with something like that, it would be forgotten within a week and wouldn't hurt their bottom line whatsoever.
Even NSA PRISM forgotten quickly
