FWIW??? Why it's worth a lot!
Premise has many drivers created with the HSDK but I know of only one or two whose source-code is available. In addition to its intended function, your driver will also serve as a reference for anyone wishing to write a new driver.
Truth be told, I tried to contact you about two years ago via an email address I found posted somewhere but I suspect my message ended up in a Junk folder (and I recognize you are a very busy guy). About a month ago, I noticed your blog had a link to the Premise/Crestron Bridge but I couldn't find the source code. Today, it's on everyone's doorstep (github). Many thanks for sharing your work with the public!
