Sowhat is a fairly closed-ended tool with a specific function that it performs quite well. We are unlikely to expand upon its basic functionality. However, we have already been begged to port this utility to Linux and this port is likely to become available in the near future. Other architectures are less likely as porting targets.
Several open questions may be attacked by future tools with differing scopes. It would be nice, e.g., to automate the process of comparing user environments and checking for homogeneity between various machines. This would be especially useful if it operated also in a heterogeneous environment, e.g., comparing commands and versions available to Solaris and Linux users.
