My post on Tira Wireless‘ apparent demise triggered a few e-mails, and it was pointed out that, whilst my observations generally seem to have been accurate, I forgot a few players that actually do deliver porting solutions across platforms (e.g. from J2ME to BREW) rather successfully (and do work with some of the larger publishers, too). There is for instance Innaworks, whose Alchemo solution is pretty powerful.
So, I stand corrected: it is actually possible to ease porting nightmares with smart transcoding solutions. I would still maintain though that porting from a single J2ME build (rather than a reference code base) to all devices under the sun is only possible with severe constraints. If that is understood though, the likes of Innaworks and Metismo provide a great ease of pain!
