I'll also check their ASCOM support. Meanwhile, Matt at Planewave allowed me to share this info with the forum:
Thanks for reaching out. We do not currently have INDI drivers for our mounts, but it is on our list for features to add. If you are interested in writing your own software we do offer a custom programming interface that can let you control the mount via a different machine on the network. i.e. using a Linux based machine to control mount software that's running on a Windows PC.

Ok, I'll guess we'll have to wait until they release a proper INDI driver. The more customers demand INDI drivers, the better. So a call out for all Planeweave users out there to email and call support regarding this.
