Oh wow, I'd forgotten writing this till your post popped up in my email. It was a side project on a contract 4 years ago where the client was cool with sharing the work with the community ( So if you like it props to Cap Logistics for paying for the initial dev and being willing to share ).
I actually just started a new job at a startup in the "constant crunch time" phase so I'm up to my eyebrows coming up to speed with their code base right now. If anyone wants to take over this plugin I'm tottally cool with that. Let me know if I have to grant permissions or anything. If not I'll put a note in my to-do list about looking at porting it to 1.8 but I won't be able to act on it probably for a month or so.
How difficult is a 1.8 port? Is it just tweaking things or did they shake things up a lot?
