I know of 2 other vendors that have the same 'attitude' Spectrosonics and Image Line.
I believe it is immoral to not allow 2nd hand sale of your product when the vendor was willing to pay for the product and every audio release is avaliable for nothing via the undegroung warez network for nothing. I suggest if you dont wish software transfers for nothing you at least offer a transter for a set fee decided for yourself - I suggest $80 for GPO perhaps????
To not allow resale of a licence will only alienate users of the product -- you must support people who are willing to pay for the product -- if you dont -- more warez probably.
I have Image Line products - I won't sell them cos they they are great but I know they are worth F**k all cos I can't sell them - so they are worth as much as the warez crap !!!
