Cross-World Housing Instances

Not sure if this has been brought up before but it's been bugging me for a while and maybe a bit of feedback will clear it up.

Do you think housing (at least the inside not out) will become more of a duty-like instance where we can create cross-world parties and invite players on the same data centre to visit/hangout/RP etc, anything really?

I wouldn't want housing to go completely instanced but if some adjustments could be made to how it is at the moment, then I was thinking it could only compliment the coss-world system. The guests wouldn't be able to use any facilities, (no different to same world guests atm) though it would be a new way to socialise with players, show them your pad or just have a party . There would be a limit to how many guests are in the house at one time perhaps a single party of 8 cross-players max or two full parties(?), possibly this could be increased in a future patch depending how it worked who knows. I'm sure the afk timer would be amended somewhat to accommodate this if it ever was considered.

Anyway just thought that players may have scattered friends on the server or some cool ones they met in a duty and want another way of meeting up.

Thoughts?
