Amy writes "Is ERDAS TITAN built on a peer to peer (P2P) network technology?
Not today. Although the ERDAS TITAN user’s experience resembles a Peer to Peer (P2P) network experience (sharing, discovering, accessing data within a network of users), by definition it is not. In ERDAS TITAN, clients rely on a proxy server – an ERDAS TITAN GeoHub — as a middleman for all communication, indexing, access and data streaming. In a P2P network clients interact directly with one another in some fashion, for activities like communication, data access and download.
GeoHubs process requests, index, stream and cache data, but do not host any data. Instead, data is maintained locally and the GeoHub acts as a relay mechanism, processing requests and streaming data between users. This inherently is an added security feature, as the GeoHub is able to manage the channels between users.
Also to note, ERDAS TITAN has no true download capability (besides the sharing of KMLs) and instead advances the notion of streaming data as a service to clients through GeoHubs.
Future plans for TITAN include enabling *optional* download capabilities and also P2P sharing for GeoHubs." Some TITAN previous stories below.

Industry: ArcGIS 9.3 Supports GIS In Adobe Acrobat 9
[+]
The mandown blog has a good overview of this weeks Adobe and ESRI talks. To sum it up, here is an excerpt from ESRI's press release : "Redlands, California—ESRI announces support for Adobe Acrobat 9 software and new geospatial capabilities available in PDF with the release of ArcGIS 9.3. ESRI has collaborated with Adobe Systems Incorporated over the past year to ensure a seamless workflow for geographic information system (GIS) professionals using ArcGIS who wish to widely distribute maps in PDF. Recipients of PDF map documents can find and display a location in the file using x,y coordinates as well as measure features directly on the map. This enabling capability enhances both existing customer workflows and creates new ones because recipients without ArcGIS can directly interact in new ways with maps using Acrobat 9."
