We are in the middle of evaluating Serv-u for sharing files with our clients. First of all i am a bit concerned about the development and new versions i am seeing of Serv-u MFT. Apart from hotfixes there haven't been a major update for several years now.
Other competitors like cerberus are doing a better job. Both can do the job we want. There is one thing i would like to see and that is an API for the web client. We want to share a file and send the password that is created for the link via SMS.
We would like to automate this. An API for the web client or someway to automate this would be a winning feature for us.
