Security :: FormsAuthenticationTicket, Role, Profile?

I assume that any Role information is being stored in the FormsAuthenticationTicket in the UserData (delimited by some character).Second, I assume that any information in the Profile is not stored in memory / session anywhere, but when you do call the profile.VARIABLE, you are in fact doing a call to the DB (although it's simplified by the fact that it knows who you are when calling etc).Assuming the above is correct, I'm trying to complete a custom membership provider. As part of this each user will have a single role. So using a full blown role provider seems to be overkill. I assume that I can write the single role into the UserData in the FormsAuthenticationTicket myself?I would like to also store a number of other small bits of information in the ticket (such as a GroupId, VendorId which are seperate from the user / role). If I wanted to do this, and the role is held in the userdata, how would I identify what is a role and what is someother persistant data I need on the application?I could use Session items for these, but this might cause issues with the web-farm, plus the amount of data is very small (3 or 4, int32 values and maybe one string).Finally, items such as Address, PostCode, Contact Phone number all seem sensible items to place in the profile ( I'm using the table provider). Is the advantage here purely the ease of access? This isn't commonly used data, so if there is a round trip to the db thats not an issue really in this instance
