I have modified the web.config file of the sharepoint virtual server to
point to a copy of the wss_minimaltrust.config that I renamed to
wss_customtrust.config. I have followed all the steps to setup the
additional permissions that I want and the code groups to identify
assemblies signed by me. So my questions are these:

1. Do I still have to put an entry into the web.config <safecontrol>
for each webpart that I deploy into the bin directory of the virtual
server.

2. If I use a <IMembershipCondition> tag with
class="StrongNameMembershipCondition", by omitting the name property I
can use the same key to sign multiple assemblies? Is this true? How
does this affect the entries in the <safecontrol> section because they
need to specify the namespace property.
