Dan,
The Electronic Literature Organization has been pondering more or less the same thing. Their PAD (Preservation, Archival, Dissemination) project
"seeks to identify threatened and endangered electronic literature and to maintain accessibility, encourage stability, and ensure availability of electronic works for readers, institutions, and scholars. PAD seems to supplement and contribute to the efforts of other projects aimed and preserving digital media, and other projects dealing with textual materials, by focusing on the particular problems of electronic literature, which can combine the complexity of a multimedia compter program with the demands of a literary text."
Maybe it would be worth talking to them?..
