Aside from OPENWRT for the WRT54G and including OLSRD, what makes the packaged versions available here "special"?

Are there particular changes to the olsrd that are not in the main branch that are needed?  Do they make the olsrd included incompatible with other implementations?

Or is it just that you've made my life easier by pre-configuring everything and making it a snap?

I have several AR670W "N" devices that use the ramips architecture.  They have sufficient RAM and flash, and they're available for $25 new.

(I also have a few AR430W which are not as easy to find now, but are decently equipped with R-SMA external antennas, convenient to attach to an external gain antenna)

I have downloaded the OPENWRT source and compiled the firmware, but without olsrd.

(I did grab the release AFTER Kamikaze, and maybe I should try the Kamikaze build)

I have downloaded the HSMM from SVN, which has olsrd, but haven't sorted out how to bring over the olsrd from HSMM into the mainline SVN dump from OPENWRT.

I have other devices capable of running olsrd, but only if it would be compatible with the olsrd included in the HSMM builds.

I've been contemplating a mesh for town since I first heard about OLSRD a few years ago, but now another ham has caught the bug and maybe it'll gain some traction.
