So from C++ to their language?
Sort of, we get 90% of the way there in terms of interop just by writing a decerver plugin: https://github.com/eris-ltd/decerver-interfaces
Putting the current business logic exactly as is onto a thelonius chain is just an option if the infrastructure becomes so mature it outpaces us and it becomes easier to maintain/develop by using their tools. BTS would be preserved exactly and the end user wouldn't need to notice.
You mean Preston (Byrne)? I think he was critical of BitAssets without price feed (in the initial phase). With the price feed and the 30 day maturity it changed quite a bit...
Yes, that's why I said too bad. I also am not sure we really got a full argument out of him. I think part of his original criticism implies he thinks BTS is too dangerous or impossible to use collateral at all / nobody would buy BTS except to do a "nonsense" trade with themselves. But practically all price-tracking proposals rely on a crypto-token being able to back other assets, and AFAIK all discussions deal with how to minimize risk for the person holding the stable token (so far we have bitassets, off-chain nushares/nubits, truthcoin PMs whose shares can be redeemed for $ value, vitalik's schellingcoin and recent bitasset-like proposals).
