In theory the DMS could run both at BF and HVL, just the price of PURCHASE would be adjusted for different sale fees (0.4% HVL, 1.-0.5% BF).
I'm not sure if it's possible, just a thought.
Yeah it's definitely possible - either with one as main and the other as a pass-through or as a dual listing (where both are considered to be of equal standing).
One of the next securities I'd been planning to list was going to be dual listed (on BTC-TC and LTC-Global) with bot-managed transfers possible between the exchanges. That would allow both markets to effectively share liquidity and would have also allowed use of the securities to arbitrage on the LTC/BTC exchange-rate.
Unfortunately if we relist on either of Bitfunder/Havelock then there's need to be unavoidable changes to the contract. There's no way around that - as neither exchange has the functionality to support all aspects of the current contract. Specific problem areas (some of which may only relate to one of them) are :
1. Lack of API support for transfers - meaning PURCHASE splits would have to be done manually so I'd have to impose limits on them to kep the workload bearable.
2. No direct transfer of BTC - so redemption of MINING+SELLING pairs wouldn't be possible (or would have to be restricted only to large bundles with the BTC paid off-exchange).
3. No voting system - so investment approval would have to be simplified. This also raises problems with the shutdown vote - which is a more serious concern that investment approval really.
None of this is insurmountable - but do be aware that in the event of a move I WOULD have to change the contract to reflect what was actually practical. Which I hate - as contracts shouldn't get changed by an issuer. But the alternative - moving with a contract that couldn't be followed because of platform limitations - is even worse.
Which is a large part of why my initial view was that closure was preferable. However that has its own issues - specifically that I then have to decide on settlement prices and people holding BOTH of MINING/SELLING are then going to feel aggrieved that they bought at a price they believed would be profitable and are now being forced to sell off without even a chance to realise that profit.
Voting at present indicates a strong preference to relist and also a strong preference for Bitfunder over Havelock. Ownership of both MINING and SELLING is pretty broad - noone owns more than 10% of SELLING, one person owns just over 10% of MINING - so those results aren't just a few large investors.
