I don't know if anyone is keeping those plugins up to date (never used Blender), but in your place I would export my Blender model to .md3 and then convert it to .mdl using Noesis, or even use directly the .md3 if your engine of choice is FTE or other supporting the format.
I know FrikaC made a cgi-bin version of the quakec interpreter once and wrote part of his website in QuakeC
