Being able to restrict portal logins by IP address would allow me to require that our users be on our work network to access our content. This would make our Information Security Officer happier about introducing another cloud service into our organization. I get that SWSD is lightweight, but I would like to be able to harden our portal a little. Restrict access by IP address seems to be a standard feature in other cloud products I use, so it seems like it might be an easy addition.
