1 or 2 miles will easily work, distance-wise with 10gR2 creating an extended RAC cluster. Tom Kyte has talked about them and there are resources available on how to set them up though none are complete from what I've seen.

While I haven't built on personally I do know consultants that have if you want a referral.

Also check out the related metalink docs at: https://metalink.oracle.com/metalink/plsql/f?p=130:14:3404545947456550968::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,220970.1,1,1,1,helvetica

and feel free to contact me off-line.
