Your mod_rewrite rules are becoming more and more interesting. Please
do post them.

There is one more drawback however I have just thought about. If I go
for a WiFi solution, I can deploy just an AP at some remote branch as
a RADIUS client of the central FreeRADIUS server.

If I go for a captive portal solution, I would need to install captive
portals at every branch, or tunnel Internet traffic via the central
hub.
