Exactly.

  UniversalResource->new("http://hostname/path/";); # HTTP
  UniversalResource->new("file://path/to/file");   # FileHandle
  UniversalResource->new("data:image/png;...");    # raw data (see URI::data)
  UniversalResource->new("ftp://user:pass@hostname/path";); # FTP

Then we can handle these resource transparently with single common
API.
