Maybe something like this? So every additional rank gets at least a little bit of a useful perk (as opposed to just more responsibility,) but the VIPs still have some meaningful advantages...
Rookie: access to /warp
Regular: 2 sethomes
Member: 3 sethomes
Experienced: [Warp] signs and creative access
Advanced: [Disposal] signs and 4 sethomes
Adept: 5 sethomes
Expert: 6 sethomes
Veteran: /co i and 7 sethomes; perhaps also add setwarps, or keep XP on death
Elite: Unchanged, or perhaps add one of previously mentioned perks
VIP1: Same, but with 9 sethomes instead of 5
VIP2: Same, but 12 sethomes instead of 10
VIP3: Same
Other thoughts: Maybe set up a high-end slot machine with unique awards that can only be accessed at certain rank/VIP level(s)?
ETA: Dunno how practical it would be to do it, or whether it would lend itself easily to abuse, but it also occurs to me that the ability to add barrier blocks might be a good perk at one of the higher levels.
