VS 2010 - How To Add Paging To Repeater That Uses Membership Provider As Datasource

I am using a custom membership provider. I needed to bind a repeater to a membershipusercollection but the only way I could think of was this:

There is no method to return a lcollection of membership users by userid. I basically have a friends table with a userid and a frienduserid field. both are foreign keys to the user table. So say I am userid 1 and I have two friends userid 2 and userid 3.

I needed to get a collection of membership users who are my friends (user 2 and 3)

So I did this:

Code:
Dim lstAccountIDs As List(Of Integer) = bl.GetFriendsAccountByUserID(iUser)
Dim mUsers As New MembershipUserCollection
For Each a In lstAccountIDs
mUsers.Add(Membership.GetUser(a))
Next

I get their id's and add them to to list(of Integer) then I loop through the list and get the particular user by id and add them to a membershipusercollection object.

I now need to add paging to my repeater control that uses that collection as a datasource. However the membership provider doesn't give me the ability to specify a pageindex or pagesize etc. It gives me those options in the GetAllUsers function but I need it to work in the above scenario.
