Wallet?
There is no "wallet," as this is not to be considered "money." These are shares in a business. The code is forked from PTS. Now, the actual Proto Shares license agreement is in flux, so this might be a false start (supposedly I'm expected to pay 10% of my business in royalties to people who invested in ProtoShares). However, I never saw this license until after I released the code, as it was not included in the original source. We'll see what happens.
I sure don't see any other stipulations in this github.
Yeah, I know, which is why it's rather frustrating talking to the people on the bitshares forums. I don't think they have any
legal standing to enforce such a restriction. The "license" is in draft. I heard about it here:
https://bitsharestalk.org/index.php?topic=2012.msg24863#msg24863. It also claims to enforce design restrictions on any forks of the protoshares code (limits total number of shares, for example).
That said, I don't want to tell them to go fly a kite. I am using their proof-of-work code. Once I get to actual share distribution, I'll probably try to work something out with Invictus.
