Another solution would fit nicely would be that all worker proposals are paid in BitUSD but this would require a hard fork.
That's not true. I proposed on several occasions to create a new multisig account (owned by the committee) that actually creates the workers for people looking to work for BitShares, gets the BTS and borrows bitUSD at ratio 3x or more) to pay them to the "employee" ...
All we need to do is to agree on this process since the shareholder needs to pay 3x - MORE for the worker in BTS terms to fund the collateral.
I'm glad you agree this would be a suitable alternative. We should look to develop this idea further.
When I said it would require a hard fork I meant for it to be done in a decentralised way.
Yes the committee-account could pay BitUSD to workers that mirrors the pay that they receive for their own worker proposals. (but this isn't very elegant)
The ultimate solution would be if all workers were paid in Bitusd that was created autonomously using the funds in the reserve pool as backing. (this would need a hard fork)
