Is there a tool for converting Smallworld data into a variety of other GIS formats?
We have a number of Smallworld instances and need to create a central repository for the data that can be used by a mobile application.

It's been about 5 years since I've worked with Smallworld first hand, so this may be outdated.
At that time, I was using version 4.1. Smallworld itself didn't, and I presume still doesn't, have any real exporting capability for spatial data outside of it's XML which uses a proprietary schema that doesn't mesh well with GML.
The only commercial option that I knew of was Safe Software's FME.
It may be overkill if all you want to do is export shapefiles, but it's quite powerful and may be useful as a general ETL tool as well.
Besides that, there is the XML that Smallworld exports (if it still does). That can be transformed into GML using XSLT, which you could then use with any number of tools to convert.
The SEPM X-Translator is easy to install and use, it offers import/export functionality for Shape, DWG/DXF, KML, Text and a few other formats. Disclaimer: I wrote this software so I may be kind of biased.
We have made good experience with FME and the SpatialBizPlugin by SBS Systems. This is a quite expensive commercial solution, as everything related to Smallworld, but it works pretty well. As an end user I can say this without any commerial interest.
Whether SEPM X-Translator is easy to install and to use or not seems strongly depending on the personal point of view, i daresay.
