Hi Tom,
This kind of a requirement can be best handled with Integration Server. If your are using webMethods 4.X integration server, You can use IS EDI module to read the flat file and convert it to XML and pass on to the service which sends the file to your customer.
This capability of handling flat files now becomes a core functionality of Integration Server in webMethods 6.
As well IS gives you better large file handling facility where in you can specify a threshold limit to treat a file as large or small.
We have used IO adapter with batch option to process large files and found EDI way as efficient and maintainable.
Hope this helps.
