I'd support a push for doing a 'CLAM'.
If and only if the cryptonote groups would include the new coin in their mining pools.

So holders of CANN POT STV DOPE BLZ THC Bongr would get a free handout of the base amount, mined there from out.

ELSE;
I would support a Vcash based market that trades the #420 pairs.

ps ... I rather not touch XCI until it has a proven track record say 400 days.  That said XCI community is free to open relations with #420.
