Ways to integrate with iSeries applications and data

I started researching methods to integrate an ASP.NET application with iSeries applications and data and found the following ways/products. This list is still in its infancy and this is not a complete evaluation just some initial observations.

1 Send CSV files and receive CSV files from iSeries
- Minimal cost
- Cumbersome
- Lot of hand-written code, hence difficult to maintain
- Takes time to implement

2 ASNA DataGate record-level access
- Has a trial offer
- iSeries native method of accessing data - record-level access

3 LookSoftware's soarchitect Product
- Claims to create web services from existing iSeries programs
- Has a trial offer

4 IBM's iSeries Access for Windows
- Doesn't support .NET 2.0 as yet.

5 Jacada HostFuse
- J2EE/JCA solution only.

6 Attunity Connect & Stream
- Connect allows querying DB2/400 data
- Allows creating web services from existing RPG programs
- Stream monitors changes and propagates it

7 RJS Software Systems iSeries data access provider
- Not looked at yet.

8 Arbutus Software
-Arbutus does not have write back capabilities. Only one way supply into ASP.NET from iSeries
