The Wifi standard Wireless Infrastructure Mode configuration needs to be supported on Nokia N95 to enable it to be used as a secure WPA WiFi Hotspot.

When will this be supported for the N95 / Symbian?

Joikuspot 3rd party software enables the N95 and other 3G Nokia phones to behave as a UNSECURE WiFi hotspot. But they can't provide secure WPA access because Symbian does not support it.

Having secure access means that you and only you can connect to the phone via WiFI, e.g. from your laptop.
