Is it actually a row identifier, like this is row 10? Reason I ask is that is what most people are looking for when they are asking about an internal rowid. Is that what this individual is asking, not sure.
Think they're talking about the RID. Row Identifier, binary value, 8-byte combination of file id, page number and slot index. It's accessible on all tables (not just heaps), however it's likely to change whenever the clustered index is rebuilt (and, on SQL 2008, if the heap is ever rebuilt) because it's the physical location of the row.
