I apologize for creating a new thread as there are already some places with complaints about this, but I hope to unify what is known and unknown about this issue and hopefully elicit an official response and help from ESRI on this matter.

I posted the following at the end of February since we were using the old RDO system (for which support has been removed since 9.4 beta): http://forums.arcgis.com/threads/1483-3rd-Party-Raster-Dll-Support-in-10?p=4980

The only official details on how to do this is here: http://edn.esri.com/index.cfm?fa=downloads.detail&downloadid=204 but I cannot even get a sample dll to load using 9.3.1 or 9.4 or 10. It scans the gdalplugins folder (I used the Procmon SysInternals utility to monitor file and directory accesses) to get the list of dlls in it but never even accesses or opens the files. There is a user comment at this link with no answer complaining about the exact same issue.

The following link complains that there is no SDK for GDAL available for 9.4/10.0: http://forums.arcgis.com/threads/844-Custom-GDAL-raster-filter-not-working-in-9.4 It does imply that they somehow managed to get this to work in a previous version, although I cannot determine how.

There is a bug in the system since November 2008 (NIM040337) that basically complains that the documentation on this is thin and that there is no working example (as we had at one point with the RDO system) that shows that this is actually working here: http://resources.arcgis.com/content/nimbus-bug?bugID=TklNMDQwMzM3
