Q: Oracle Remote

I have to put up a link between the RDBMS and a remote client. For now I now have come up with four possibilities:

1. Make copies from the database and use 3rd party software (Access, Dbase) at the remote site.
2. Personal Oracle (not a link, but it will do)
3. Another client in the network with a modem connection to the remote
4. A dial in box from HP, creating a remote console

None of the above is exactly what I'm looking for, since I also want to use all Windows facilities for the client. Can someone please help me with this?

Our hard- and software:

HP 9000, UNIX 10.0
HP Vectra client 486/66/16MB
TCP/IP network protocol

Oracle      7.1.4
SQL*Plus    3.1     (windows+ux)
PL*SQL      ?
SQL*Net
SQL*Forms   4.0     (windows)
SQL*Reports 2.0     (windows)
