It is quite OK to install web apps/contribs into ibays, there is nothing dangerous about doing that.
The "Interestingly dangerous" comment made earlier, I believe was in regard to allowing a developer to upload & overwite files & to overwite your mysql databases, allowing that sort of access could be considered dangerous.
There was comment made many years ago to install web contribs to /opt, rather than ibays, so many contrib coders went that way, but the insistence on doing that was eased in later comments.
AFAIK there is no really strong reason not to install web apps to ibays.
Both /opt & ibays have issues, as allowing web access is really a compromise on security wherever you place web accessible files.
The other issue raised re ibays, was that users could access the ibay & corrupt files or change configs etc, so any ibays that have web contribs in them, should have restricted access to LAN users, ie a seperate Group is created for ibays that are web sites, so only a tech administrator (Group) can access the files using samba etc.
ibays were designed on smeserver (then e-smith) to be used for web content.
