Dave Well, the ECW-JPEG 2000 SDK is free from ER Mapping. I'm not 100% sure whether the security implementation (JSEC) is available within this, but it's easy enough to check. ER Mapping have good response to enquiries, and there are several public forums linked to from their main website.
Then, it would certainly be possible for you to write what's needed within your application to unlock files, but MapInfo (and probably few standard GIS products) would accept a bitstream - they expect a disk file. So, you would have a transient on-disk file which is "a security risk" (ie, someone could swipe it).
