Jenson Chen, the software project manager for Plustek Inc, announced last week they're looking to collaborate with the SANE (Scanner Access Now Easy) project. They are looking to provide the driver source-code for integration into SANE so that it can have out-of-the-box support on various Linux distributions.
The request for thoughts on this proposal can be found via this mailing list thread. I haven't seen Plustek post any source code yet, but it's promising that it's looking like they intend to and for it to be open-source Linux support rather than yet another scanner manufacturer just shipping binary blobs. Hopefully we'll see some code soon enough. I wasn't familiar with this scanner brand prior to seeing this mailing list thread but a quick Amazon search reveals many Plustek products in the US, particularly when it comes to film scanners.
