SSIS: JOINING TABLES FROM TWO SERVERS - BETTER WAY THAN SORT -&&> MERGE JOIN?

Setup:

I need to run an Insert query which pulls data from a table located on server A database AA Table AAA conditional on (or JOINED with) Table BBB in database BB sever B. In SQL 2000 it could be done as:

From Server A:
sp_addlinkedserver B
INSERT dbo.ResultsTable
SELECT SourceTable.* FROM B.BB.dbo.BBB SourceTable
INNER JOIN A.AA.dbo.AAA ConditionTable ON SourceTable.RecID = ConditionTable.RecID
sp_dropserver B


In SSIS one of the possible solutions is to use a package which does the following:
OPEN A + OPEN B-> SORT A + SORT B->MERGE JOIN A and B->OUTPUT RESULT

The problem with this approach is that it's extremely slow for large datafiles (50M records each)

Questions:

1) In the procedure above could the SORT step be avoided?
2) Is there another approach to run cross-servers JOIN in SSIS?

Thank you
